After applying of this patch series I see the following compilation 
issue for kernel:
     | ERROR: modpost: vmlinux: local symbol 'security_path_rmdir' was 
exported
     | make[2]: *** 
[/home/ok/Projects/yocto/build/tmp/work-shared/radxa-zero-3e/kernel-source/scripts/Makefile.modpost:145: 
vmlinux.symvers] Error 1
     | make[1]: *** 
[/home/ok/Projects/yocto/build/tmp/work-shared/radxa-zero-3e/kernel-source/Makefile:1871: 
modpost] Error 2

     | make: *** 
[/home/ok/Projects/yocto/build/tmp/work-shared/radxa-zero-3e/kernel-source/Makefile:240: 
__sub-make] Error 2


Should I apply something except the patches from these patch series? 
Otherwise I think we should disable some security things ( as a 
workaround ):

CONFIG_SECURITYFS=n CONFIG_SECURITY_NETWORK=y 
CONFIG_SECURITY_NETWORK_XFRM=n CONFIG_SECURITY_PATH=y 
CONFIG_SECURITY_LANDLOCK=y

Best regards,
